ZSCT1555N8TA

Overview

The ZSCT1555N8TA is a precision single-cell timer IC manufactured by Diodes Incorporated, housed in an SO-8 package. It operates from a supply voltage range of 0.9V to 6V with a typical quiescent current of 74μA at 1.5V. The device supports monostable and astable modes, featuring internal threshold and trigger levels set as proportions of VCC. Key electrical parameters include a maximum propagation delay of 2μs, a discharge switch on-state voltage of 350mV max at 0.3mA, and an output low voltage of 1V max at 100mA sink current.

Feature Summary

Operates from a single battery cell with a minimum supply voltage of 0.9V
Very low quiescent current of 74μA (typical) for power economy
Pin connections comparable with standard 555 series timers
Available in SO-8 (N8) and DIL-8 (D8) packages

Applications

Portable and battery-powered equipment
Low voltage and low power systems
Single cell boost converters generating regulated supplies

Procurement Notes

Verify the N8 suffix corresponds to the SO-8 package configuration. Confirm RoHS compliance status as the provided datasheet does not explicitly state it for this specific part number variant. Ensure the ordering code matches the manufacturer's current nomenclature for the tape and reel quantity indicated by the TA suffix.

Selection Notes

Select this component when timing accuracy is required at low voltages below standard 555 timer limits. The device maintains frequency independence from supply voltage variations in both monostable and astable configurations. Consider the 74μA typical supply current for battery life calculations and ensure external timing components are selected within the recommended resistance ranges to minimize leakage effects.

Part Context

The ZSCT1555 series is designed as a low-voltage alternative to traditional bipolar 555 timers. Originally developed by Zetex Semiconductors, the product line was acquired by Diodes Incorporated. The N8 designation specifically identifies the Surface Mount (SO-8) package variant within the family.
